RankSVM for Offline Signature Verification
2019 International Conference on Document Analysis and Recognition (ICDAR), 2019Signature verification systems suffer from imbalanced learning, which imposes strict requirements on classifiers. The standard classification approaches, such as SVM, often degrade the performance for imbalanced data or require additional parameters for data balancing.

Signature barcodes for online verification
Pattern Recognition, 2022Abstract As a sub-branch of behavioral biometrics, online signature verification systems deal with unique signing characteristics, which could be better differentiated by extraction of habitual singing styles instead of geometric features in case of perfect forgery. Even if the signatures are geometrically identical, speed and frequency components of

A hybrid system for signature verification
Proceedings of the IEEE-INNS-ENNS International Joint Conference on Neural Networks. IJCNN 2000. Neural Computing: New Challenges and Perspectives for the New Millennium, 2000Biometric authentication has become a popular research topic due to its wide applicability, including the prevention of fraud in financial transactions. Handwritten signature verification, in contrast with other biometric based authentication methods such as fingerprint and retinal scanning, has the advantage that it is already widely used to endorse ...

A Survey of On-line Signature Verification
2011Signature is a commonly accepted biometric feature for individual identification. On-line signature has begun to prevail in the last decades for it exploits dynamic features which traditional off-line signature fails to preserve. This paper presents a review of researches on on-line signature verification during recent years and lists some of the works

Batch Verification of EdDSA Signatures
2014In AfricaCrypt 2012 and ACNS 2014, several algorithms are proposed for the batch verification of ECDSA signatures. In this paper, we make a comparative study of these methods for the Edwards curve digital signature algorithm (EdDSA). We describe the adaptation of Algorithms N, N′, S2′ and SP for EdDSA signatures.

Quick Verification of RSA Signatures
2011 Eighth International Conference on Information Technology: New Generations, 2011Speeding up RSA signature authentication is important in various scenarios. We propose here a scheme for quick verification of RSA signatures, that is mostly appropriate when the public exponent is small. This scheme pre-computes the quotients required to perform modular reduction during verification, and includes them as part of the certificate that ...

Signature Schemes with Randomized Verification
2017A signature scheme consists of a setup, signing and verification algorithms. In most existing works, the verification algorithm is assumed to be deterministic. However, there could be signature schemes where the verification algorithm is randomized. In this work, we study signature schemes with randomized verification.

Batch Verification of ECDSA Signatures
2012In this paper, we study several algorithms for batch verification of ECDSA signatures. The first of these algorithms is based upon the naive idea of taking square roots in the underlying field. We also propose two new and efficient algorithms which replace square-root computations by symbolic manipulations.
